Description

Represents an event triggered when a caption edit operation begins.

This event is triggered when a caption edit operation begins as result of a call to EditText or after the user pressed F2 to go into edit mode. Set the AllowEdit parameter to False to prevent the editing operation from starting.

Write an OnEditing event handler to determine whether the user is allowed to edit the caption of a specific base item in the TCategoryButtons class.

The parameters expected by OnEditing are listed in the following table:

Argument	Meaning
Sender	Represents the TCategoryButtons control that the button belongs to.
Item	Represents the TBaseItem (button or category) whose caption was edited.
AllowEdit	Set to False to prevent the editing from starting.
